Introduction
Channel steel is a long elbow-shaped structure for bridges. It is a plain structural steel used in construction and machinery. It is a steel structure with a complex cross-section, and its cross-section shape is elbow-shaped. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc.
Classification
1.Channel steel is divided into ordinary channel steel and light channel steel.
2.According to shape:
(1)Cold-formed equal-edge channel steel
(2)Cold-formed unequal-edge channel steel
(3)Cold-formed inner curled channel steel
(4)Cold-formed outer curled channel steel
Fundamental State
In use, it is required to have good welding, riveting performance and comprehensive mechanical properties. The raw material billets for producing channel steel are carbon steel or low alloy steel billets with a carbon content of no more than 0.25%. The finishedchannel steel is delivered in a hot-formed, normalized or hot-rolled state.
The specifications are expressed in millimeters of height(h) width(b) thickness(d). For channel steel with the same height, if there are several different widths and thicknesses, a,b,c must be added to the right of the model number to distinguish them, such as 25#a 25#b 25#c, etc.
Standard:ASTM A6/A6M-12
Material
1.Stainless Steel: S31254, 904L, 347H, 317L, 310S, 309, 316Ti, 321H, 304L, 304H, 316L, 316H
2.Duplex Stainless Steel: UNS S31803, S32205, S32750, S32760
Specifications
The specifications of channel steel are mainly expressed by height(h),width(b),thickness(d) and other dimensions. The specifications of domesticchannel steel range from 5-40, that is, the corresponding height is 5-40cm. At the same height, light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. No.18 to 40 are large channel steels, and No.5 to 16 are medium channel steels.
The delivery length of channel steel is divided into two types: fixed length and double length, and the tolerance value is specified in the corresponding standard. The length selection range of domestic channel steel is divided into three types according to different specifications:5-12m,5-19m,and 6-19m.The length selection range of imported channel steel is generally 6-15m.
